Parallel Forall is curated by Mark Harris, Chief Technologist for GPU Computing Software at NVIDIA. Mark has over ten years of experience developing software for GPUs, ranging from graphics and games, to physically based simulation, to parallel algorithms and high-performance computing. Mark has used GPUs for general-purpose computing since before they were up for the task—before they even supported floating point arithmetic! As a Ph.D. student at UNC he developed real-time cloud simulation and rendering software for GPUs (simulating clouds, not simulation in “the cloud”!). In 2002 Mark recognized a nascent trend in computing and coined a name for it: GPGPU (General-Purpose computing on Graphics Processing Units), and started GPGPU.org to provide a forum for those working in the field to share and discuss their work. GPGPU.org has grown into a top destination for information about GPU computing.

Today, GPU computing truly is a mainstream technology. World-changing science problems are being solved on GPUs. Many of the Top500 fastest supercomputers in the world rely on GPUs. GPUs can be programmed using the most popular programming languages, and there are dozens of open-source and commercial GPU-accelerated libraries available. GPU computing today is a growing industry with a mature ecosystem of applications, tools, and service providers.
